Suppan will go for a rare home win when St. Louis opens a three-game series against the Cincinnati Reds.
Suppan has been outstanding away from Busch, going 7-0 with a 2.76 ERA in 10 starts. But things have not worked out nearly as well for him at home as he is 3-6 with a 4.84 ERA in 12 outings.
The 29-year-old right-hander had struggled in his first four starts following the All-Star break before shutting down defending World Series champion Florida on Wednesday. Suppan allowed only two hits over eight-plus innings as the Cardinals defeated the Marlins 1-0.
Suppan, who walked two and struck out two, took a no-hitter into the sixth inning.
“I was able to keep the goose eggs going,” said Suppan, who improved to 10-6. “I tried to throw strikes and use the defense.”
The Cardinals have won nine of their last 11 to stretch their lead in the NL Central to 13 1/2 games over the Chicago Cubs.
Scott Rolen homered twice to become the first NL player to reach 100 RBIs this season as St. Louis beat Atlanta 10-4 on Sunday. It was Rolen’s fifth multihomer game of the season and the 18th of his career.
The Reds have dropped six of their last nine, including a 7-2 loss to San Diego on Sunday.
Dunn went 0-for-5 with three strikeouts and left six on base.
First baseman Sean Casey was the offensive star for the Reds, going 3-for-5 with a double and a homer. He’s hitting .408 in August to raise his overall average to .341.
